Formatting numbers in 'Current' and 'Hi/Lo' Reports

[Peter Fletcher]

Is there a way in the relevant .inc files of overriding the default numeric formatting (which seems to be) defined by the group a data value is included in? The predefined power group appears to want to use one decimal place, and no thousands separator. Because of the magnitude of the numbers I am displaying, I would like to have whole numbers with a thousands separator. The customization section of the manual does not seem to address this particular aspect of customization.

Whole numbers can easily be specified with a custom format. Something like:

$week.power.sum.format("%.0f")

Unfortunately, use of thousands separators depends on the specified locale and cannot be overridden. It really should be.

I have implemented a workaround by putting in conditionals to display power values greater than 1000W as kW, which avoids the thousands separator issue. The whole thing is a bit odd, because my locale is US, which I thought should be using the separators by default.
